Chapter 72 (Iron and Steel) of the HTS defines stainless steel as follows:
Note 1(e): “Alloy steel containing by weight 1.2% maximum carbon and 10.5% minimum chromium, with or without other elements.”
Further defined in the HTS is Section XV (Base Metals) Interpretive Note 5(a), which provides:
“An alloy of base metals is to be classified as an alloy of metal which predominates by weight over each of the other metals.”
Stated in more simple terms: if iron, versus nickel, is the predominant element and meets the Note 1(e) definition then the alloy is stainless steel and should be classified in Chapter 72 versus improperly classifying it in Chapter 75 as a nickel-based or nickel-bearing alloy.
